An equipment enclosure for electrical or electronic equipment (1) has a door (7) which can close off the interior chamber (8). The door (7) is fitted with a heat exchanger having separate internal and external air circuits with the internal air circuit connected with the interior chamber (8) and the external air circuit connected for a supply of entering air and for the exhaust of air outside of the enclosure (1). The heat exchanger enables the temperature within the chamber (8) to be kept at a required level relative to the ambient temperature external of the enclosure (1). |
